Abstract
The challenge of modern industries is mainly focused on the achievement of high quality, in terms of work dimensional accuracy, surface finish and higher MRR. Wire EDM machines are used to cut conductive metals of any hardness or that are difficult or impossible to cut with traditional methods. Wire EDM uses a very thin wire 0.02-0.03 mm in diameter as an electrode and machines a workpiece with electric discharge like a bandsaw by moving either workpiece or wire. The prominent feature of moving wire is that a complicated cut-out can be easily machined without using a forming electrode. This machining process is not limited by hardness, toughness and brittleness of the material and can produce intricate shape on any workpiece by suitable control over the physical parameters of the processes Machine tool industry has made exponential growth in its manufacturing capabilities in last decade but still machine tools are not utilized at their full potential. The main problem arrives in this process is the proper selection of parameters so as to utilize the process capability to full its potential. As in case of wire EDM, the limitation arises due to poor MRR and higher surface roughness which has attracted the attention of the researchers and practising engineers.
